Hi,
We've been thinking about adding support for the built-in functions for 64bit atomic memory access and I'd like to know if this is of any interest. Currently the main use of these functions seems to be to implement (SMP safe) locking mechanisms where the existent 32bit memory ops are sufficient. However, there might be code out there that implements a parallel algorithm using 64bit atomic memory operations.
I've been told (though I've not verified it) that the Membase NoSQL database needs 64-bit atomic operations to work effectively (http://www.membase.org/downloadsrc)
Interesting... ..Thanks!
